Laravel Homestead: No input file specified

I swear I've read over every single article of documentation that has ever existed on setting up homestead, and I just cannot seem to get past this issues. I really have tried everything that I can find. The Homestead documentation is horrendous...

I've tried vagrant --provision and every other command-line recommendation available, it seems.

Homestead.yaml
